I'm always suspicious of claims of extraordinary gains from very old technology, and this is no different, but I don't understand the physics well enough to make a serious case for why. I figured someone on HN would debunk it, though I don't think that's entirely happened yet in this thread. Then again, the people making extraordinary claims are the ones with the responsibility to provide extraordinary evidence, which they clearly haven't done. But, Popular Mechanics is excited about it, so it must be awesome. Those guys are all about bearings. Anyway, this should be perfect for my perpetual motion machine. Less friction means it'll run for more forevers before it stops.
